CASA GRANDE, Ariz. – The bodies of two adults and a child were found after a house caught fire northeast of Casa Grande Friday morning.

The Pinal County Sheriff's Office and the Regional Fire Department responded to a fire in an unincorporated area of Pinal County around 6:30 a.m.

Deputies and firefighters arrived at the home near the intersection of Paseo Del Sol and Henness Road in the Desert Highlands subdivision, and found it fully engulfed. The Casa Grande and Gila River fire departments were called to assist.

While identities have not been officially confirmed, the Sheriff's Office said a prominent doctor in the community, Dr. Joyce Bonenberger, 51, lived at the address. Her husband, Dennis Edward Brough, 50, and their 11-year-old son, Trevor, also lived in the home.

Sheriff's Office spokesman Tim Gaffney said both of their vehicles were still at the house.

The bodies were found in different parts of the home. An adult male was found in the garage, an adult female in the master bedroom, and a child in another bedroom.

The Sheriff's Office said the Medical Examiner's Office will have to confirm the identities through dental records.

Autopsies will be performed to determine the cause of death for each person.

Bonenberger has served as the Chief of Surgery at Casa Grande Regional Medical Center for the past nine years. She has been a member of the hospital's medical staff since July 1999.

The hospital said Bonenberger helped pioneer a breakthrough treatment for early-stage breast cancer.

"Dr. Bonenberger was a beloved member of the CGRMC Medical Staff," said hospital CEO and President Rona Curphy. She was a surgeon who made a real difference in the lives of many patients and staff members in our community. She will be remembered for her sense of humor, willingness to train medical students, and her interest in improving the lives of her patients through surgical interventions. Her contributions to CGRMC are invaluable.”

Bonenberger also had a private practice, where her husband worked as the office manager, according to friends.

"Her office was just always real cheerful," said Jessica Haney, who works in the medical office next door. "Everyone in there was always smiling. They're all good people, so this has been real tragic."

"Dr. Bonenberger was a very good doctor; very sympathetic to my husband," Haney added.

Rev. Ben Seller of First Presbyterian Church, where the family attended services weekly, described the family as loving and extremely close-knit. He said they had been deacons in the past.

"They were always together," he said. "They traveled together all the time. They very rarely were they apart."

Seller said the community is in shock.

"I think the whole community is grieving," he said. "I think we're feeling a sense of loss."

The Sheriff's Office said neighbors called 911, and tried to kick down the door and break windows to see if anyone was inside.

"There was just too much smoke," said neighbor Frank Chirumbolo, whose son had tried to help.

The first emergency responders arrived at the home within 10 minutes of the call being dispatched, and the home was already full engulfed in flames, the Sheriff's Office said.

"I've never seen a house burn like that," Chirumbolo said.

The entire four-bedroom house was leveled.

Due to the damage, it will take time to process the scene and investigate the cause of the fire, according to Gaffney. Investigators have not ruled out foul play.

"We're securing all evidence," Pinal County Sheriff Paul Babeu said. "We still don't know at this time what fully happened."
